| attrition |
The loss of subjects during the course of a study. This may be a threat to the validity of conclusions if participants of study and comparison/control groups drop out at different rates or for different reasons. FOR EXAMPLE, if treatment participants fail to appear for treatment and are subsequently excluded from the follow-up, the treatment and control subjects remaining may not be "comparable" due to attrition.
